Question

Eli5:why we use the solar calendar instead of the lunar calendar?

In: Planetary Science

Answer 1

Lunar calendars track the brightness of moonlight, basically. Solar calendars track the change of entire seasons and are more useful for planting crops and timing winter migrations. And lastly, the lunar calendar does not precisely line up with the solar calendars. There are cultures that still celebrate holidays every 12th lunar month, but those holidays get earlier every year and can drift between seasons enough to be VERY different from year to year.
